Pump gears20 and 21, arranged'infmeshing relatio'n, :are held`between the end :of "the body and the flanged end 17 of the body'zexten- `525 Vsionby means'of the-"sleeve, yAzpassage 23 is drilled 'lengthwise of .the 1'body ian'dwestablishes communication `between the radial fbore113eand the u pump Achamber fand another passage 124 "drilledinto" the pump fend of thebody andfis con- @so nected the axial bore .11 of the .body rby means of fthe' transversely extending passage'i25. Fluid 4`flows from the reservoir 15 :through 'the borejl' and passage 23 to the pump :chamber The axialbore 11 in theb'odyis` threadedffand -`a 'tubular nozzle element 26 is screwed therein." This nozzle element is provided witharestricted 40 outlet opening 27 and providesa conduitithrough whichtheifiuid is movedfrom theax'ial bore 11 Afto be deposited upon the surface overvwhich' the instrument is' moved. A needle 'memberZBfeX- ltends' through the .nozzle and-is Aof smaller I111i-, ameterl so that it will .permit `the passage A`of 'fluid Vthroughthe nozzle. `The outer end .29;01.

`theneedle is reduced in diameterjand.is'ofagsize such'thatrit` providesl a restrictionv to 'the f-flow fof iiuid through the nozzle solthat adesiredspread offfluid isfdeposited Aas the instrument is:moved along the vsurface to be striped. The .projecting endiof the needle member is roundedjandserves 4as :the vdevicev :bearing 'for :engaging the surface of the needle and the outlet end of the nozzle must be calculated carefully because when such distance is too great, the fluid being forced through the nozzle will move out in large drops causing an uneven stripe, and when the distance is too small there is a capillary attraction which results in an uneven stripe or a wider stripe than is desired. f -Y Heretofore it was customary to fix the.; needle element to the interior of the body and when the end thereof was ground or stoned to maintain it more round, the distance between the end of the needle and the nozzle end would-be decreased so that eventually the instrument would .have

to be discarded because ofthe capillary attraction between the surface and the nozzle during the iiuid iiow which caused the stripe to be deposited in an uneven widthl and considerably wider than intended. In order to overcome .this gdif- 20. culty and to materially increase the life of a device'of Vthis character, I provide means for adjustably securing the needle, and to'this end I press the needle intofa securing element 30 which is screwed into the end of the bore 11. adjacent the bore 12. When the `handle 14 isremoved .from the body, the securingmember for the needle can be screwed axially so that the Vdistance between the end of the needle member and the outward end of the nozzle can be arranged a de- .30 nite distance apart. In this manner the proper spacing of'the nozzle outlet end from the'surface to be striped can'be readily provided upon the initial assembly of the device, and can be maintained after each stoning or .grindingfop- 140 racljustably securing the needle will materially increase the life of an instrument of this charac- .ten` and will also insure that a desired width, of -stripe will be produced upon the surface along `:which the bearing end of the needle member is 2,45 lnOVed."

A sleeve 31 .surrounds .a portion of thek nozzle anduextends interiorly of the body extension 16. The interior end of such sleeve is xed to the gear 21 in any suitable manner andthe end of 5 0 the sleeve projecting beyond the bodyextension is in the form of a wheel 32. Roller bearings 33 arearranged between the outer end of the body extensionand the sleeve and are retained enclosed .by the roller member. A key 34. extends through the body member and projects into a .circular'groove 35 formed in the sleeve, such arrangement serving to retain the roller-and its 1 sleeve in Va denite'axialwrelation with the body .iextension.Y .A spacer 22 is arranged intermediatev the bodyend and the extension iiangegand vis retained by the pins 36.

" The roller 32 is 'adapted togbear against a .-beadingor raised flange portion adjacent a'surface to beYV striped and when theV yneedle mem- 165 ber 4bears against such surface andthe instrument-is moved lengthwise of the. beading, the

" roller 32 will'be rotated and will transmit such u rotation to the pump gears so that fluid is moved through 'the pumpl chamber .and 'thence through .70 r`thenozzle where itwill pass bythe valve memi175 *mentof the.V device along thebead, and consethe nozzle outlet end, an axially. adjustable member screwed into the bore,'said member beingk quently a uniform amountl of iluid will `be deposited along the surfaceV irrespective of the speed at which the device is operating and, therefore, a stripe of a uniform quantity and width will result. Y

It will be seen'that the pump will move uid through the nozzle commensurate with theY speed so that a uniform` volume is deposited upon the'V surface to be striped regardless of the speed, and a uniform application of .fluid moving lthrough 10 the nozzle in this manner is insured because of Ytheadjustable securing arrangement for the needle member which maintains the nozzle end Vproperly spaced from the work to be striped under allcircums'tances and without the necessity of replacingany parts.
